When I went to Disney WORLD (which was, admittedly, back in 1985 or 1986), you couldn't. Maybe it was closed or something. Maybe Disney World's version isn't open but Disney Land's version is. I have no idea. All I know is that I still had a good time at the park and it didn't matter.
I dunno. I just see a lot of stuff online that seems hell-bent on rooting for the ultimate failure of all things Star Wars that post-date 2012, including gleeful predictions of how poorly Galaxy's Edge will do/is doing, and how much of a faceplant the ST is and blah blah blah.
Every review I've heard from every person who's been to Galaxy's Edge has been nothing but positive. They all loved it and thought it was really cool. Nobody was bitching about how you couldn't go into the big Falcon, how you were on some unknown planet, how much drinks cost, etc. It was just a cool theme park where they had a good time.
To be clear, I'm not saying that everyone here has been negative about it at all, let alone to the degree I describe, but I think a lot of the negative takes that I've seen here (and especially those I've seen elsewhere) are pretty overblown. And I don't buy the predictions of its imminent demise.
